Description

The present invention monitors the travel position of a vehicle that transports waste, and when traveling out of a predetermined travelable area, notifies a predetermined person of the travel of the waste transport vehicle. The present invention relates to a position monitoring system.

  Industrial waste and other waste are required to be properly managed from the collection site to the disposal site for the purpose of environmental protection. In order to realize proper management, proper disposal at collection sites and disposal sites is required, and proper management is also required during transportation. For example, management must be performed so that illegal dumping does not occur during transportation. Don't be.

  Therefore, in Patent Document 1 to Patent Document 3 below, position information of a vehicle or the like that transports waste is acquired by GPS or the like, the position is compared with a predetermined traveling route, and predetermined traveling is performed. An invention is disclosed in which a warning or the like is issued when a route or a predetermined area is deviated.

JP-A-9-142609 JP 2003-44576 A JP 2003-312808 A

  The conventional travel route monitoring systems as disclosed in Patent Documents 1 to 3 are useful in that a warning is issued when a predetermined travel route or a predetermined area is deviated. In particular, the system disclosed in Patent Document 1 that issues a warning when the vehicle deviates from a predetermined range without being limited to the travel route is not tied to the travel route, so the driver of the vehicle carrying the waste This is useful because the degree of freedom increases.

  However, the system disclosed in Patent Document 1 merely defines a predetermined area, and the predetermined area is considered to be a fixed range. In other words, the area that can be traveled should change according to various regional characteristics such as location, area, road conditions, traffic congestion, etc., but if it is simply a fixed area defined from the beginning, it reflects the regional characteristics. Absent.

  Further, if the vehicle deviates from the predetermined range, only the manager (transportation company) is notified. In this case, when the traveling route deviates from a predetermined range due to receiving an instruction such as illegal dumping from the manager (transportation company), the system using the invention described in Patent Document 1 has any benefit. Does not exhibit sex. That is, when the manager is actively involved in illegal dumping, the invention of Patent Document 1 is not very effective.

  In view of the above-described conventional problems, the present invention monitors the position of a vehicle that transports waste by GPS, and notifies a predetermined person when it deviates from a predetermined travelable area. In addition, the present invention has invented a position monitoring system for a waste transport vehicle, which does not fix the predetermined travelable area but makes the predetermined range more efficient.

  In addition, the inventors have invented a position monitoring system for a waste transport vehicle that notifies not only the manager but also the discharge company when a warning deviates from the predetermined range.

  The invention of claim 1 is a position monitoring system for a waste transport vehicle that monitors the position of a vehicle that transports waste, and the position monitoring system for the waste transport vehicle calculates a travelable region of the vehicle. Area calculation means, area storage means for storing the calculated travelable area, position information reception means for receiving the position information of the vehicle, and travel stored in the area storage means based on the received position information When the position information comparing means for determining whether or not the vehicle deviates from the possible area and the position information comparing means determine that the vehicle has deviated from the drivable area, the monitoring is performed. An abnormality notification means for transmitting at least a notification to an administrator terminal used by a manager who is using the waste and a discharge company terminal used by the waste discharge company. Calculates a linear equation A between the two points based on the coordinates of two predetermined points, and sets a range constituted by the allowable range dd from the linear equation A as a travelable region, a waste transport vehicle Is a position monitoring system.

  By configuring as in the present invention, unlike the conventional technique in which the travelable area is simply determined as a fixed value, an efficient travelable area can be determined. This is because the shortest distance between the two points is the straight line, and an area constituted by the allowable range is the most efficient travelable area.

  Furthermore, when the vehicle deviates from the travelable area, the administrator is not only notified to the administrator who monitors the vehicle as in the conventional case, but is also notified to the waste discharging company. The illegal dumping that the driver conspires with can be prevented. This is very beneficial to the fact that waste management companies are also required to have management responsibility. This is because the notification is also given to the discharge operator, which prevents the driver from illegally dumping out of the travelable area, and even when conspiring with the driver and the administrator This is because it is possible to ask the manager and the driver for an explanation because the discharge company knows that it has deviated from the travelable area.

  In the invention of claim 2, the travelable area includes a linear expression A ′ and a linear expression A ″ obtained by translating the linear expression A from the linear expression A by a distance dd within the allowable range, and each of the two points. Is a position monitoring system for a waste transporting vehicle, which is an area formed by a semicircle having a radius dd centered at.

  The travelable region in the above is best configured as in the present invention. The reason why the semi-circular area having the radius dd centered at two points is also set as the runnable area instead of the rectangular area constituted simply by the linear expression A ′ and the linear expression A ″ is that in an actual road, This is because the vehicle may travel in the opposite direction.

  According to a third aspect of the present invention, the position information comparison unit converts the received vehicle position information into coordinates T of a predetermined coordinate system, and the converted coordinates do not exist within the range of the travelable area. Is a position monitoring system for a waste transport vehicle that determines that the vehicle has deviated.

  Position information obtained by GPS is latitude and longitude information. If it is as it is, it is difficult to compare with the travelable area in the above coordinate system. Therefore, the comparison may be made after the vehicle position information is converted into the coordinates of the above-described coordinate system as in the present invention.

  According to a fourth aspect of the present invention, when the transportation between the two predetermined points is the first time, the area calculation means uses a value that is accepted as an initial value of the allowable range as a value of the allowable range dd. When the transportation between the two predetermined points is set for the second time or later, the permissible of the distance dg of the vehicle position from the linear formula A calculated by the area calculation means in the transportation before that time. This is a waste monitoring vehicle position monitoring system in which the largest dg with a value less than or equal to the range dd is set as the allowable range dd.

  The allowable range may be input as an initial value when traveling between two points for the first time, but in the case of traveling for the second time or later, when traveling between the two points in the past, The distance that is farthest from the straight line A is preferably set as an allowable range. Usually, the initial value is generally larger than an assumed value, and therefore, it can be corrected by an actual running and an appropriate allowable range can be set. The newly set allowable range is preferably smaller than the conventional allowable range dd. This is because an allowable range that is as narrow as possible leads to prevention of illegal dumping.

  According to a fifth aspect of the present invention, when the abnormality notifying means determines that the vehicle is out of the travelable area in the position information comparing means, the driver used by the driver of the vehicle is further used. This is a waste monitoring vehicle position monitoring system that transmits a notification to a terminal.

  Notifying the manager and the exhausting company as well as the driver can notify the driver that he / she has deviated from the driveable area, and can urge the driver to be aware that the vehicle is being monitored. It becomes a deterrent to dumping.

  According to a sixth aspect of the present invention, when the abnormality notification is performed, the abnormality notification means stores at least a position and a time of the vehicle, and the position monitoring system for the waste transport vehicle further includes: Transporting waste to a disposer, and having transport completion report means for creating a report of transport completion when transport is completed, the transport completion report means stored in the abnormality notification means, It is a position monitoring system for a waste transport vehicle, in which the position and time of the vehicle when an abnormality notification is made are described in the report.

  Thus, the reliability of the report can be improved by describing as evidence that there has been a notice of abnormality in the report of completion of transportation.

  The invention according to claim 7 is a position monitoring program for a waste transporting vehicle that is executed by a computer terminal having at least a storage device for storing information and a processing device for executing the arithmetic processing of the program, the position of the waste transporting vehicle. The monitoring program has at least an area calculation function, a position information reception function, a position information comparison function, and an abnormality notification function that are read into the arithmetic device, and the area calculation function is based on the coordinates of two predetermined points. The linear equation A between the two points is calculated, and a range constituted by the allowable range dd from the linear equation A is calculated as a travelable region of the vehicle, stored in the storage device, and the position information reception The function receives the position information of the vehicle, and the position information comparison function calculates the travelable area stored in the storage device based on the received position information. It is determined whether or not the vehicle has deviated, and the abnormality notification function performs the monitoring when the position information comparison function determines that the vehicle has deviated from the travelable area. A waste monitoring vehicle position monitoring program that transmits at least a notification to an administrator terminal used by an administrator and a discharge company terminal used by the waste discharge company.

  A program that realizes the above-described waste monitoring vehicle position monitoring system on a computer terminal can be configured as in the present invention.

  In the invention according to claim 8, the travelable area includes a straight line A ′ and a straight line A ″ obtained by translating the straight line A from the straight line A by a distance dd within the allowable range, and each of the two points. Is a position monitoring program for a waste transporting vehicle, which is an area formed by a semicircle having a radius dd centered at.

  The travelable region in the above is best configured as in the present invention. The reason why the semi-circular area having the radius dd centered at two points is also set as the runnable area instead of the rectangular area constituted simply by the linear expression A ′ and the linear expression A ″ is that in an actual road, This is because the vehicle may travel in the opposite direction.

  According to a ninth aspect of the present invention, the position information comparison function converts the received vehicle position information into coordinates T of a predetermined coordinate system, and the converted coordinates do not exist within the range of the travelable area. Is a waste monitoring vehicle position monitoring program for determining that the vehicle has deviated.

  Position information obtained by GPS is latitude and longitude information. If it is as it is, it is difficult to compare with the travelable area in the above coordinate system. Therefore, the comparison may be made after the vehicle position information is converted into the coordinates of the above-described coordinate system as in the present invention.

  In the invention of claim 10, when the transportation between the two predetermined points is the first time, the area calculation function uses a value that is accepted as an initial value of the allowable range as a value of the allowable range dd. When the transportation between the two predetermined points is set for the second time or later, the permissible of the distance dg of the vehicle position from the linear formula A calculated by the area calculation means in the transportation before that time. This is a waste monitoring vehicle position monitoring program in which the largest dg with a value less than or equal to the range dd is set as the allowable range dd.

  The allowable range may be input as an initial value when traveling between two points for the first time, but in the case of traveling for the second time or later, when traveling between the two points in the past, The distance that is farthest from the straight line A is preferably set as an allowable range. Usually, the initial value is generally larger than an assumed value, and therefore, it can be corrected by an actual running and an appropriate allowable range can be set. The newly set allowable range is preferably smaller than the conventional allowable range dd. This is because an allowable range that is as narrow as possible leads to prevention of illegal dumping.

  According to an eleventh aspect of the present invention, when the abnormality notification function determines in the position information comparison function that the vehicle is out of the travelable area, the driver who uses the vehicle further uses the abnormality notification function. This is a position monitoring program for a waste transport vehicle that transmits a notification to a terminal.

  Notifying the manager and the exhausting company as well as the driver can notify the driver that he / she has deviated from the driveable area, and can urge the driver to be aware that the vehicle is being monitored. It becomes a deterrent to dumping.

  In the invention of claim 12, when the abnormality notification is performed, the abnormality notification function stores at least the position and time of the vehicle in the storage device, and the position monitoring program for the waste transporting vehicle further includes: The vehicle has a transport completion report function for generating a report of transport completion when the vehicle transports waste to a disposal company and transport is completed, and the transport completion report function is stored in the storage device. The position monitoring program for the waste transporting vehicle, wherein the position and time of the vehicle when the abnormality notification is made is described in the report.

  Thus, the reliability of the report can be improved by describing as evidence that there has been a notice of abnormality in the report of completion of transportation.

By adopting the configuration as in the present invention, it is possible to set an efficient travelable area, not just a fixed travelable area. Further, since the notification is given not only to the manager but also to the discharge company and the driver, illegal dumping by the driver of the vehicle based on the instruction from the manager can be prevented.

  A conceptual diagram of the present invention is shown in FIG. Fig. 1 shows that the location information of the vehicles that transport the waste collected from the discharge company is sequentially sent to the center server, transported to the processing company, and after the transport is completed, the transport completion report is passed to the discharge company. ing.

  An example of the system configuration of the present invention is shown in the system configuration diagram of FIG. FIG. 3 shows a hardware configuration diagram of a normal computer as well as a server.

  The computer terminal shown in FIG. 3 has at least an arithmetic unit 21 such as a CPU and a storage unit 22 such as a RAM or a hard disk. In addition, the computer terminal further includes an input device 20 such as a keyboard and a mouse, a display device 24 such as a display, a printing device 25 such as a printer, and other computer terminals and portable terminals via a network such as the Internet. A communication device 23 is provided.

  A program that realizes the position monitoring system 1 is stored in a storage unit 22 such as a hard disk of the computer terminal, and is read into a RAM or the like when a predetermined operation is performed. By executing this at 21, the processing of the position monitoring system 1 is performed. Information used for these processes is stored in a storage unit 22 such as a RAM or a hard disk in various storage formats such as a database or a data file, and the process is performed by appropriately reading out during the process. In addition, the processing result is also written to the storage unit 22 such as a RAM or a hard disk and stored as appropriate. Each means in the present invention is only logically distinguished in function, and may be physically or practically the same area.

  The position monitoring system 1 includes an area calculation means 2, an area storage means 3, a position information reception means 4, a position information comparison means 5, an abnormality notification means 6, a transportation completion report creation means 7, and a map information storage means 8. Yes.

  The area calculation means 2 is a means for calculating a travelable area between two predetermined points. When the vehicle deviates from the calculated area, an abnormality notification is performed. The two points for calculating the travelable area may be two arbitrary points, but are preferably two points including the position of the discharge company and the position of the processing company.

  This area can be calculated as follows. When the position S on the discharge company's coordinates is (x1, y1) and the position E on the processor's coordinates is (x2, y2), the linear expression A between SE is calculated. This is the shortest distance between the two points. A range composed of an allowable range dd that allows the vehicle to deviate from the straight line A with the straight line A as a center is a travelable region of the vehicle. In addition, when the straight line expression A is expressed by a mathematical expression, it becomes as follows. FIG. 6 shows a conceptual diagram of the area set in this way.

（但しx1≦x≦x2，y1≦y≦y2） In other words, the travelable area includes a straight line A ′ and a straight line A ″ obtained by translating the straight line A by the allowable range dd from the straight line A represented by Equation 1, and a half of the radius dd centered on the position S and the position E. It is an area composed of circles. This area is a coordinate system represented by a predetermined point on the map, for example, the southernmost end of Okinawa as the origin O (0, 0). It should be noted that the reason why the rectangular area constituted by the straight line A ′ and the straight line A ″ is not simply set as the travel route on the actual road when going from the position S to the position E is temporarily headed in the opposite direction. This is because it is possible. Therefore, a semicircular area having a radius dd centered on the position S and the position E is also set as the travelable area.

(However, x1 ≦ x ≦ x2, y1 ≦ y ≦ y2)

In addition, the allowable range dd from the linear equation A accepts an input of a predetermined value (for example, 1 km, 3 km, 5 km, 10 km, 30 km, 50 km) from the input device 20 when transport between SEs is the first time. However, in the second and subsequent times, the maximum value dg _max of a value dg described later when traveling between SEs before that time is set to dd.

  The area storage means 3 is a means for storing the area calculated by the area calculation means 2 (information on the travelable area configured by the linear equation A and the allowable range dd).

  The position information receiving means 4 is means for receiving the position information of the vehicle carrying the waste. The vehicle position information may be received from a GPS receiver installed in the vehicle, or may be received from a mobile terminal (driver terminal 11) used by a driver of the vehicle. In the following description, these are collectively referred to as vehicle position information.

  The position information comparing means 5 converts the vehicle position information (latitude and longitude information) received by the position information receiving means 4 into the coordinates of the above-mentioned coordinate system, and the converted coordinates are stored in the area storage means 3. It is a means to determine whether it is located in the driving | running | working possible area | region to do.

  As a result of the determination in the position information comparison unit 5, the abnormality notification unit 6 determines that the position of the vehicle is outside the area, and the administrator terminal 9, the discharge company terminal 10, and the driver terminal 11 This is means for notifying that the vehicle is running out of the area. This notification is preferably performed by e-mail with respect to a preset e-mail address used by the administrator, an e-mail address used by the discharge company, and an e-mail address used by the driver. If there is an abnormality notification, the position, time, and notification destination are stored.

  The transportation completion report creating means 7 is a means for creating a report that the transportation is completed when the vehicle transports the waste to the disposal company and the transportation is completed. The completion of the transportation may be performed by a predetermined operation, or automatically when the position information received by the position information receiving means 4 matches the position information of the disposal contractor or is within a predetermined range. You may judge. Moreover, when an abnormality notification is made during transportation, the position, time, and notification destination may be described together. The report may be transmitted to the discharge company by e-mail or the like, or printed on a paper medium by the printing device 25 and mailed to the discharge company.

  The map information storage means 8 is a means for storing the map information around the vehicle and the coordinates of the main point (for example, the discharge company, the disposal company) in the coordinate system.

  Next, an example of the processing process of the position monitoring system 1 of the present invention will be described with reference to the flowcharts of FIGS. First, the manager inputs from the manager terminal 9 the work instruction of the vehicle that transports the waste, that is, which discharge company collects the waste and to which disposal company the waste is transported. It is assumed that information (position information, coordinate information, etc.) regarding the waste business operator and the disposal contractor is registered in advance.

The area calculation means 2 calculates the area from the discharge company to the disposal contractor thus input (S100). At this time, if the transport from the discharge company to the disposal contractor is the first time, the allowable range dd used for the calculation by the area calculation means 2 is set to an arbitrary value. A maximum value dg _max of a value dg described later when traveling is assumed to be dd.

  This area can be calculated as follows. When the position S on the discharge company's coordinates is (x1, y1) and the position E on the processor's coordinates is (x2, y2), the linear expression A between SE is calculated. This is the shortest distance between the two points. A range constituted by a range dd that allows the vehicle to deviate from the straight line A with the straight line A as the center is a movable region of the vehicle. In addition, when the linear formula A is expressed by a mathematical formula, it is as shown in Equation 2. FIG. 6 shows a conceptual diagram of the area set in this way.

（但しx1≦x≦x2，y1≦y≦y2） In other words, the travelable area includes a straight line A ′ and a straight line A ″ obtained by translating the straight line A from the straight line A represented by Equation 2 by an allowable range dd, and a half of the radius dd centered on the positions S and E. It is an area composed of circles. This area is a coordinate system represented by a predetermined point on the map, for example, the southernmost end of Okinawa as the origin O (0, 0). If it is known in advance that the vehicle will travel only in a predetermined area, the maximum area of the traveling area is the coordinate system on the map, and the left corner is the origin O (0, 0). It may be expressed in a system.

(However, x1 ≦ x ≦ x2, y1 ≦ y ≦ y2)

  The travelable area calculated in S100 is stored in the area storage means 3.

  In this way, after calculating the travelable area of the vehicle, the vehicle contacts the discharge company and collects the waste and starts transporting it to the disposal contractor (S110). During this transportation, the position information receiving means 4 periodically receives the position information of the vehicle (S120).

  When the position information of the vehicle is received in S120, the position information comparison means 5 determines whether or not the vehicle has deviated from the travelable area (S130). This determination in the position information comparison means 5 is performed as follows.

  First, the position information comparison means 5 converts the vehicle position information (latitude and longitude information) received by the position information receiving means 4 into the coordinates of the coordinate system described above (S200). Let the coordinate T of the vehicle after conversion be (xg, yg). Then, it is determined whether or not this coordinate T exists within the travelable area calculated in S100.

Specifically, the position information comparison unit 5 calculates a perpendicular line A (straight line expression B) passing through the coordinates T (S210). This linear formula B is expressed as in Equation 3. Note that the coordinates of the intersection C between the linear equation A and the linear equation B are (xn, yn). This state is shown in FIG.

Next, the position information comparison unit 5 calculates the coordinates (xn, yn) of the intersection C (S220). In this case, it is only necessary to calculate the intersection point between the linear equation A and the linear equation B, so the coordinate C of the intersection point is expressed as shown in Equation 4.

  The position information comparison means 5 calculates dg by trigonometry with the shortest distance between the coordinate T and the intersection C as dg (S230).

  Then, the coordinate T converted in S200 intersects the travelable area calculated in S100 (the linear equation A ′, the linear equation A ″, the linear equation A ′ and the linear equation A ″, and the position S and the position E are It is determined whether or not it exists in an area formed by a semicircle having a radius dd as the center (S240). If it exists within the area, it does not deviate from the travelable area, so the process proceeds directly to the next process. If it exists outside the area, it is determined that the vehicle has deviated from the travelable area (S250).

Furthermore, compared with the dg calculated in the maximum value _{dg max} (where _{dg max} ≦ dd) and S230 in dg between SE _(S260), replaces the value of dg calculated in S230 the _dg max <dg if _{dg max} (S270). By making such a comparison, it is possible to calculate an efficient travelable region when actually traveling without exceeding the region possible range. Then, if the dg _max is set as the dd at the next travel time, the region after the next time can be calculated as an optimum one.

  As described above, when the position information comparison unit 5 determines that there is a region deviation as a result of the determination from the execution of the processing from S200 to S250 (S140), the abnormality notification unit 6 determines that the administrator terminal 9 and the discharge business The driver terminal 10 and the driver terminal 11 are notified that the vehicle is traveling outside the region (S150). This notification is preferably performed by e-mail with respect to a preset e-mail address used by the administrator, an e-mail address used by the discharge company, and an e-mail address used by the driver. If there is an abnormality notification, the position, time, and notification destination are stored.

  In this way, while the vehicle is carrying the waste, the position information and the travelable area are compared each time the position information is received (S160). The vehicle then transports the waste to the disposal company, and when the transportation is completed, creates a report that the transportation is completed (S170). The completion of the transportation may be performed by receiving a predetermined operation input, or the position information received by the position information receiving means 4 coincides with the position information of the disposal contractor or is within a predetermined range. It is also possible to make a determination automatically. Moreover, when an abnormality notification is made during transportation, the position, time, and notification destination may be described together. The report may be transmitted to the discharge company by e-mail or the like, or printed on a paper medium by the printing device 25 and mailed to the discharge company.

  In the above-described first embodiment, the case from one discharge company to one disposal contractor has been described, but even if there are a plurality of these, the same can be realized. That is, each region between two points may be calculated and the region may be compared with the position information. A conceptual diagram in this case is shown in FIG.

  In the case of FIG. 8, after waste is collected by the discharge company A, the waste company B and the discharge company C sequentially collect the waste, and then the disposal company D disposes of the waste. . Even in this case, the processing between the two points in the first embodiment may be combined. Specifically, first, the discharge company A is set as the start point S1, the discharge company B is set as the end point E1, and the area is set as the area possible range dd1, and then the discharge company B is set as the start point S2 and the discharge company C is set as the end point E2. The area is set in the area possible range dd2, and the area is set in the area possible range dd3 with the discharge company C as the start point S3 and the disposal contractor D as the end point E3. Even if there are a plurality of points in the travelable area set in this way by comparing the position information between the points with the position information of the vehicle being transported, it is possible to monitor the transport status. The area possible ranges dd1, dd2, and dd3 at this time may be the same value or different values.

  For example, when the driver moves from the discharge company A to the discharge company B and further moves from the discharge company B to the discharge company C, the travelable area must be changed. By receiving from the driver terminal 11 that the work on the discharge company B has been completed from the driver of the vehicle, the travelable area to be compared by the position information comparison means 5 is determined from the discharge company A. What is necessary is just to change from the discharge | emission company B to the drive | workable area | region of the discharge | emission company C from the discharge | emission company | B In addition to receiving the completion of work from the driver terminal 11 in this way, the vehicle reaches the discharge company B because the position information of the vehicle is the same as or within a predetermined range of the discharge company B. It may be determined that the travelable area is changed from the travelable area of the discharge company A to the discharge business B to the travelable area of the discharge business B to the discharge business C.

By adopting the above-described configuration, it is possible to set an efficient travelable area, not just a fixed travelable area. Further, since the notification is given not only to the manager but also to the discharge company and the driver, illegal dumping by the driver of the vehicle based on the instruction from the manager can be prevented.
